Peter Regin will officially become an unrestricted free agent on Tuesday, but he and the Chicago Blackhawks still haven't ruled out a return to the team next season, according to Regin's agent.

"Still talking with Chicago," Regin's agent Craig Oster of Newport Sports Management wrote in an email Tuesday. "They have many moving pieces and all are related because of the cap."

The 28-year-old Regin could provide Blackhawks depth at center and wing as he did last season. He didn't play consistently for the Blackhawks after arriving from the New York Islanders in a trade in February, but he had positive performances when he was in the lineup. He had a Corsi (shot differential) of better than 50 percent in 11-of-17 regular-season games. He finished with two goals, two assists and was a plus-5 in 17 regular-season games and had zero points and was a minus-1 in five playoff games for the Blackhawks.

Blackhawks general manager Stan Bowman said Friday re-signing Regin and defenseman Sheldon Brookbank were still possibilities.

"We've talked about a lot of options," Bowman said. "I haven't ruled anything out at this point. We just got the exact number today. We're going to do our homework and plan out some things and make some phone calls leading into July 1. We got an idea what we want to do."
